tcptraceroute is a setuid-root program which drops root
privileges after obtaining a file descriptor used for raw packet
capture. However, it did not fully relinquish all privileges, and
in the event of an exploitable vulnerability, root privileges could
be regained.

No current exploit is known, but this safeguard is being
repaired in order to provide a measure of containment in the event
that an exploitable flaw should be discovered.

For the stable distribution (woody) this problem has been fixed
in version 1.2-2.

The old stable distribution (potato) does not contain a
tcptraceroute package.

For the unstable distribution (sid) this problem is fixed in
version 1.4-4.

We recommend that you update your tcptraceroute package.
